You could do this with Scheduling, absolutely!
Create appointment types for each time range. Set the duration for 240 minutes (4 hours, based on your examples)
Go into the Availabilty and adjust the settings.
Set up the time ranges for each appointment type to limit it during the day.
You can also edit the "Appointments Per Time Slot" setting to limit how many people can book during each time slot. So if you could deliver to 4 addresses in your delivery range during that time, set it at 4, or adjust as needed.
